0. GENERAL

0.4 Health & safety

Electric safetyDo not carry out any maintenance operation on the pump while it is running or before it has been dis-connected from the power supply. Avoid any danger caused by electric power (for details see current regulations in force). Check that electrical specifications on the data plate are equivalent to the power supply to which it will be connected.

Chemical hazardsAvoid pumping liquids, even in different moments that may cause chemical reactions without having cleaned the pump.

Dry runningDo not start nor carry out running tests before filling the pump with liquid. Always avoid the dry opera-tion of the pump. Start the pump when it is completely filled with the delivery valve almost fully closed, limiting this condition to the time that is strictly necessary to start the pump.

Temperature hazardsThe cold or hot parts of the machine must be protected to avoid accidental contacts.

Rotating partsDo not tamper with the protection of the rotating parts, do not touch or approach rotating parts in movement.

Noise levelCT pumps, including the motor, in normal operating conditions produce a sound level below 80 dB(A). The major sources of noise are: liquid turbulence in the plant, cavitation or any other abnormal opera-tion that do not depend from the pump construction nor the pump manufacturer. The user must provide suitable protective means if the sources of noise could produce a harmful noise level for operators and for the environment (in compliance with current regulations).

Cleaning & disinfectionCleaning and disinfection of the pump system is of greatest importance when the pump is used in a food process installation. Use of a pump system that is NOT cleaned or disinfected can cause contamination of the product.

1. INSTALLATION

1.1 Receiving inspectionAlthough precaution is taken by us when packing and shipping, we urge you to carefully check the ship-ment on receipt. Make sure that all parts and accessories listed on the packing list are accounted for. Immediately report any damage or shortage to the transport company and to us.

1.2 StorageIf the equipment is to be stored prior to installation, place it in a clean location. Do not remove the protective covers from the suction and discharge which have been fastened to keep pump internals free of debris. Make sure to clean the pump thoroughly before installation.

1.3 FoundationThe pump-motor unit must stand on and be fixed to a sufficiently rigid structure that can support the entire perimeter on which the unit stands. The foundation on a firm bottom are the most satisfactory. Once the pump is in position, adjust level with metal shims between the feet and the surface on which it stands. Check that the feet of the pump-motor unit stand well on each of them. The surface on which the foundation stands must be flat and horizontal. If the unit is fitted on a steel structure, make sure that it is supported so that the feet do not warp. In any case, it is advisable to fit some antivibration rubber pieces between the pump and the brickwork.

For close-coupled type, pump-motor alignment is not required.

1.4 Piping connectionsA pump is generally part of a piping system that can include a number of components such as valves, fittings, filters, expansion joints, instruments, etc. The way the piping is arranged and the positioning of the components has a great influence on operation and the operating life of the pump. The pump can-not be used as a support for the components connected to it.

The flow of liquid from the pump must be as even as possible. It is advisable to avoid any tight bends or drastic reductions of diameters that may cause flow resistance in the plant. In case of diameter reduction, it is advisable to use appropriate conical reductions (possibly eccentric on suction side and concentric on delivery side) at changes of diameter and at a minimum distance from pump inlets of five diameters.

1.4.1 Discharge pipeA nonreturn valve and a shutoff/regulation valve are normally fitted on the discharge side.The nonreturn valve protects the pump from any backflow. The shutoff/regulation valve excludes the pump from the line and adjusts output. Never adjust flow-rate using the valve on the suction pipe.

1.4.2 Suction pipeThe suction piping is very important for the correct operation of the pump group. It must be as short and as direct as possible. If a longer suction line is unavoidable, the diameter should be large enough, i.e. at least as the inlet connection on the pump, to ensure less flow resistance. In any case, suction must be carried out properly avoiding any air locks.

The CT pumps are single-stage centrifugal type, thus not self-priming. It will therefore always be necessary to install a bottom valve in all cases when the static height of the liquid is lower than the suction height of the pump. The suction piping must be without air inlets that are more probable with long suction lines or if suction occurs with negative head. Critical points in these terms are also the seals between flanges and the seals of the valve stems. Even some small air let into the suction line cause serious operating problems that can make the pump stop.

1. INSTALLATION

1.6 InstrumentsIn order to ensure a reasonable control of the performance and the conditions of the pump installed, we recommend using the following instruments:

- a pressure-vacuum gauge on the suction piping;- a pressure gauge on the delivery piping.

The pressure intakes must be made on straight pieces of piping at minimum five diameters from the pump inlets. The pressure gauge on delivery must always be fitted between the pump and the shutoff/regulation valve. The output can be read on the pressure, transformed into meters and then compared with the typical curves.

Electric powerThe electric power absorbed by the motor can be measured with wattmeters.

Optional instrumentsThe optional instruments can advise of abnormal operating conditions of pumps, such as: valves closed accidentally, missing liquid, overloads, etc.

ThermometerIf the temperature of the pumped liquid can be a critical element, provide a thermometer (preferably on suction).

1.7 Motor ConnectionAn expert electrician must always carry out the electrical connection. Compare the power supply with the data plate specifications and then choose a suitable connection. The type of connection is stated on the motor data plate that can be Y (star) or D (Delta), according to the power supply of the motor (see figure).

Star connection Y Delta connection D

Follow the prescriptions of the local electricity board for the connection. In no case connect the electrical motors directly to mains but also fit in between a suitable electric switchboard equipped with a knife switch and suitable safety devices. Safety devices against overloads must protect the motors. Make sure that the motor has suitable grounding and that it has been connected properly.

2. OPERATION

2.1 Start-up

- Check manually that the motor is free to turn, moving the motor cooling fan.

- Make sure that the piping is not clogged and is free from residues or foreign objects. Make sure that the liquid flows regularly into the pump.

- The pump and piping connected to it, at least the suction pipe, must be full of liquid. Any air or gas must be carefully released. In case of suction with negative head, fill the suction piping and check how the bottom valve works. It must guarantee that the liquid must not flow back, emptying therefore the suction pipe with consequent disconnection of the pump.

- The suction shutoff valve (if any) must be completely open.

- The shutoff/regulation valve on the discharge side must be almost completely closed.

- The motor must turn in the same direction as the arrow shown on the pump. The direction of rotation is always clockwise looking at the pump from the motor side; check by starting briefly, then looking at the direction of rotation of the motor fan through the fan lid. If it is wrong, the motor must be stopped immediately. Change the connection to the terminals of the electric motor (chapter 1.7) and repeat the procedure described above.

- Any auxiliary connections must all be connected.

2.1.1 Starting the pumpStart the electric motor and open the discharge adjustment/shutoff valve gradually until the desired output has been reached. The pump must not turn more than two or three minutes with discharge closed. A longer operation in these conditions can damage the pump seriously.

If the pressure shown on the pressure gauge on the discharge piping does not increase, turn off the pump immediately and release pressure carefully. Repeat the connection procedure.

If there are changes of flow-rate, head, density, temperature or viscosity of the liquid, stop the pump and get in touch with our technical service.

2.1.2 Re-starting after power shutoffIn case of accidental stopping, make sure that the non-return valve has prevented backflow and check that the motor cooling fan has stopped. Start the pump again following the instructions of chapter 2.1.1 ”Starting the pump”.

If the pump intakes from a lower level, it can unprime during the standstill and therefore you must check again before starting that the pump and the suction piping are full of liquid.

2.2 Stopping the PumpIt is advisable to close the discharge adjustment/shutoff valve gradually and stop the motor immediately after. The reverse sequence is not recommendable, especially with larger pumps or longer delivery piping. That is to avoid any problems due to water hammering. If a suction shutoff valve has been installed, it is advisable to close it completely.

2.3 Cleaning and disinfectionCleaning and disinfection of the pump system is of greatest importance when the pump is used in a food process installation. Use of a pump system that is NOT cleaned or disinfected can cause contamination of the product. The cleaning cycles as well as chemicals to use for the cleaning vary depending on the pumped product and the process. The user is responsible to establish a suitable cleaning and/or disin-fection program according to local and public health and safety regulations.

2.3.1 Cleaning procedureThe pump may be cleaned in two different ways:

CIP (Cleaning In Place)without dismantling the pump, using steam, water or cleaning chemicals. Follow these safety instructions during the CIP procedure:

- Make sure that all cleaning line connections are properly tightened to avoid splashing of hot water or cleaning chemicals.

- When using a automatic process, a safety device should be installed to avoid unintentional automatic start-up of the pump.

- Make sure that the connections in the pump system are secure and tight.- Before any disassembly of the pump, fittings or pipes, make sure that the cleaning cycle is finished.

Manual cleaningby simply dismantling the pump casing, impeller and mechanical seal. Always follow these safety in-structions:

- Switch off the electric power to the motor and disconnect the motor starting system if installed.- The cleaning personnel shall wear suitable protective clothing, footwear and goggles.- Use a suitable non-toxic and non-inflammable cleaning solution.- Always keep the area around the pump clean and dry.- Never clean the pump by hand with pump running.

3. MAINTENANCE

Maintenance work on electrical installations must be performed by qualified personnel and only when the power supply has been shutoff. Follow the local and national safety regulations.

3.1 Inspections- Periodically check suction and discharge pressures. - Inspect the motor according to the instructions from the motor manufacturer.- In general, a mechanical seal does not require maintenance, but the pump should never run when

empty (dry). If a leakage occurs, replace the mechanical seal.

3. MAINTENANCE

3.5 Lubricated seal

A great option where there is a potential risk of dry running, or where the product tends to solidify or crystallize. An oil chamber is connected to the mechanical seal chamber.

The pump is delivered without lube medium in oil chamber!

- Before the first start fill up the oil chamber with proper medium (i.e. SAE 20 oil). In case the pumped medium can’t be contaminated by oil, you should use a lubricating medium compatible with pumped medium. - Medium in the oil chamber should be also compatible with materials that the pump is made of (when using oil as buffering liquid you should not use EPDM O-rings in mechanical seal) - NBR lip seal is a standard (other materials are available upon request). - Oil chamber should be filled up to ¾ of oil cup height. - You should change oil after 2000 hours of operation or once a year.

Important!

- If mechanical seal damage will occur, fluid level in the chamber will increase and then it will spill out of the oil cup. You must stop the pump immediately to replace mechanical seal! - If oil level in oil cup will start decreasing in short period of time, probably lip seal is damaged. You should stop the pump and replace damaged lip seal.

3. MAINTENANCE

3.6 Heating/cooling jacket

Great protection for the mechanical seal in cases where there is a risk for solidification of the pro-duct. The heating jacket is also used when the pumped product has to maintain a specific tempe-rature, high or low. A heating or cooling medium is continuously circulated in the jacket.

Back casing heating/cooling system is available in sizes: “C” , “D” and "E" of Tapflo CT pumps. Heating/cooling is operated by a jacket placed in pump back casing (12). The jacket have two G ½” connections. To connect the jacket use flexible hose to prevent any undue stress and strain on the heating jacket connectors.

For heating/cooling process use medium fully compatible with materials the pump is made of.

Maximum temperature for heating medium is 60°C, maximum pressure is 2 Bar. It’s crucial to avoid sudden temperature changes that could cause excessive strains.

3.7 Flushed seal

When abrasive or sticky particles are present, it’s recommended to use flushed seal (plan 11). A small amount of the pumped product is recirculated from the discharge side to the seal chamber to flush solids cumulated in it. It helps to save mechanical seal (15) and back casing (12) from being worn. In addition a self-cleaning filter is used at the discharge.
